Label 1 among Fig. 1 always refers to the gas/liquid separation device assembly according to the first embodiment of the present invention.-as, assembly 1 comprises: a container 4 is pressure vessel 5 in this example, it comprises shell 6 and lid 7; And one be received in inner dismountable and that change or maintainable separator unit 9, comprises a single maintainable separator element or a separator unit 10 in this example.Specific separator 10 shown in can understanding is flow separation devices 11 from proceeding to out.O shape ring sealing between lid 7 and the shell 6 is shown as label 8.Lid 7 is by bolt 7a fix in position.

In general, pressure vessel 5 comprises a gas inflow entrance 12, a gas flow export 13 and fluid discharge outlet 16.In operation, a gas communication that wherein has liquid is crossed the inside 18 that inlet 12 is incorporated into assembly 1.Gas stream finally is incorporated into an interior zone 10a of separator 10 in assembly 1.At last, gas passes through media pack 20 from the inside 10a of separator 10, outwards passes through, passes through in this example gas flow export 13 from pressure vessel 5 then.

Ad hoc structure shown in Figure 1 uses a flow separation device unit 11 that proceeds to out, this means that they lead to a perimeter 21 (as shown in arrow 22) from the inside 10a (formed and surrounded by media pack 20) of separator 10 when gas passes through the media pack 20 of separator unit 11.

Still with reference to Fig. 1, for shown in specific components 1: inlet 12 is sidewall inlet 12a, this means that it extends through sidewall 5a; Outlet 13 also is sidewall outlet 13a, this means that it extends through sidewall 5a, and exhaust outlet 16 is bottom exhaust outlets.So-called " bottom " is meant in the literary composition: when being orientated typical use as shown in Figure 1, and the bottom 23 of bottom finger assembly 1.Term " sidewall " is meant the shell wall part 5a that extends between the lid 7 and the end 23.

For the ease of operation, assembly 1 forms the upper area 25 of a sealing and the lower area 26 of a sealing usually, and in this example, they are separated by tube plate structure 28.Tube plate structure 28 generally is solid not have the hole to exist for the gas stream by wherein, is exception in the specific zone of regulation only.Tube plate structure 28 forms a centre bore 33 in this example.Except hole 33, tube plate structure 28 is generally solid and preferably comprises: an annular installing ring 35; One sagging center wall 36 is a cylindrical wall 36a in this example; And the bottom 37 that has centre bore 33.Bottom 37 is attached in the lower limb 36b of wall 36.One upper sump 39 (will discuss hereinafter) is roughly formed on wall 36 and bottom 37.It will be appreciated that from detailed description hereinafter hole 33 provides a mobile passage for the gas stream that enters upper area 25 (specifically in separator unit 9) from lower area 26.

Center wall 36 is preferably a radially continuous wall.So-called term in the literary composition " radially continuous " is meant that it is continuously around central axis 47 extensions.Specific (special) requirements wall 36 is not cylindrical walls.Yet when assembly 1 comprises one when being used for the single separator element of separator 10, such structure will be easily.

Lower area 26 comprises lower sump region 40, and showing in this example wherein has liquid (oil) 41.Before gas entered in the upper area 25 by hole 33, the many liquid that initially comprise were discharged to lower sump region 40 by gas inflow entrance 12.

Still with reference to Fig. 1, assembly 1 comprises temperature probe port 42, level instrumentation nozzle 43, lower sump filling pipe 44, relief valve aperture 45 and pressure tap 46 in zone 26.The pipe 44 alternative inlets that provide liquid to enter lower sump 40 are provided, so that operation (if necessary), for example, when assembly 1 was put on the pipeline for the first time, relief valve aperture 45 authorized pressures controlledly discharged by the relief valve (not shown).Temperature probe port 42, level instrumentation nozzle 43 and pressure tap 46 are used for surveillance equipment.Specific size, quantity and the position of adapter and

hole

42,43,44,45 and 46 are the thing of a selection for the specific operation that will carry out.The position of liquids in general fill port 44 is higher than level instrumentation nozzle 43.Usually release port 45 is positioned at the top of lower area 26, preferably is communicated with (will summarize hereinafter) with inlet stream ring cavity fluid ground.Release port 45 is presented among Fig. 1 with respect to the radial position (around central axis 47) of inlet 12, and it turns over about 180 °.One radial position that is more preferably will be discussed hereinafter.

With reference to Fig. 1, in hole 40, the liquid level 41a of operating liquid (oil) is shown.In common use, be included in the oil masses of hole in 40 and be a thing of selecting a suitable oil mass, it causes a desirable mean temperature or a chilling temperature, suitably the guiding oil mechanical system of getting back to described compressor from floss hole 16.The temp probe that is provided with by port 42 can be used to monitor this process.

One takes over 46a also by the location of the sidewall 5a in the zone 25, is used for measuring the pressure in this zone.

As mentioned above, separator 10 is one dismountable and removable (that is, maintainable) parts.Separator 10 comprises the media pack 20 (being a columniform media pack 48 in this example) that is fixed at one end on the end cap 50.For specific components shown in Figure 1, end cap 50 is the end cap 50a that close, and this means the hole that it is not communicated with the inside 10a of separator 10.

At end 55 places relative with end cap 50, separator 10 comprises that one wherein has the end cap 56 of centre bore 57.In use, centre bore 57 is holes of a gas flow, so that gas is by entering in the inner 10a.In general, align with hole 33 in hole 57, so that the gas conduction that passes through hole 33 in from zone 26 to zone 25 is in the inside 10a of separator 10.

Various hermetically-sealed constructions can be used in junction between separator 10 and tube plate structure 28.For example, can use radial seal or axial seal or they both.In example shown in Figure 1, used a radial seal structure.

Specifically, in centre bore 57, be provided with sealing ring 58 cause with bottom 37 on the radial seal of cylindrical projection 60.Protuberance 60 forms centre bore 33 together with bottom 37.For example, sealing ring 58 can comprise O shape ring 62.Sealing ring 58 prevents usually that escape of gas from going out that inner 10a enters in the zone 21 and by media pack 20.

The radial seal of another variation can comprise the part of a columniform protuberance (replace protuberance 60) as the one of end cap 55, make radial seal center on protuberance outside abuts against bottom 37 remainder and form.

With reference to Fig. 1, should be noted that, the axial length of separator 10 be slightly shorter than cover 7 and bottom 37 between distance.In use, remove by an opening and to cover 7, separator 10 is installed in pipe or protuberance 60 tops with hand.Then, lid 7 can be in place.Under operating pressure, separator 10 is setovered usually, supports to bump against up to it and covers till 7.Radial seal structure is configured to allow such motion and does not have loss of seal.The structure of this sample loading mode is convenient to the manufacturing of separator 10, because the manufacturing tolerance closely on the length will not be crucial.

The term " radially " that relates to sealing used herein means and is used for towards radially outward or a sealing of locating away from the pressure of central axis 47.Here combination seal and the term " axially " that uses mean and use a sealing of carrying out towards the sealing force of the roughly direction of the longitudinal extension of axis 47.For example, O shape ring 8 provides an axial sealing.

In general, if separator 10 is provided with an axial seal, it is outwards outstanding vertically from end cap 56 that a sealing ring then is set usually.Sealing will be positioned to engage the bottom 37 of a part in seal process.Need one to provide the structure of pressure to guarantee sealing.This pressure can be provided by lid 7 or other structure.

The special construction of media pack 20 is not crucial for the General Principle of inlet deflection plate described here, just the thing of a selection.In general, the size of media pack 20 and structure will be selected according to following all projects: air stream, the level of efficiency that requires, acceptable limit amount, preferred service life and available space size.

For example, the media pack of air/oil separators is described in U.S.6, and 093,231; 6,136,016; WO99/47211; U.K.1,603,519; U.S.6,419,721; And 4,836,931, this paper quotes above-mentioned whole disclosure for your guidance.For example, the principle of the structure of these types can be applied to separator unit herein.

The media pack of separator 10 generally includes coalescent layer 63 in a upstream and downstream drain layer 64.Because separator 10 is " proceeding to out ", so coalescent layer 63 is discharged layer 64 and surrounds.Can use various inner lining structures or scrim structure to come convenient assembling or operation.In general, in coalescent layer 63, the fine liquid particle that is carried in the gas stream carries out coalescent.Coalescent liquid particles is driven in the drain layer 64 usually, then, is discharged in the zone, hole, upstream 39 from drain layer 64.One purification pipe or tubular construction 68 are shown as and are projected in the upper sump 39, so that the liquid that discharging is collected from zone 39.

Still with reference to Fig. 1, pressure vessel 5 has the bottom 72 of a columniform outer wall 71 and a circle.Columniform outer wall 71 forms central axis 47, and it passes through the center 75 of rounded bottom 72 usually.

In general, the gas/liquid separation device of type described here is provided with one of gas access structure of two types.One be referred to as usually in this article tangential gas access first the inlet be have a center line with respect to circle or cylindrical outer wall roughly towards tangential gas access.Accompanying drawing of the present invention does not illustrate one and tangentially enters the mouth, but traditional inlet can be used for the principle of many announcements.In general, compare with the gas access of second type of hereinafter discussing, the shell with tangential inlet is made relatively costly.Therefore, preferably avoid adopting tangential outlet for the reason of cost.

The gas access of second type shown in Figure 1 usually is referred to as the inlet of " radially " or " radial direction ".The special inlet 12 that is shown among Fig. 1 is inlets 77 of radial direction.Usually, the inlet 77 of radial direction is such Way in, makes the central longitudinal axis 47 of gas stream generally toward pressure vessel 5.For shown in specific example, the center line 78 of gas access 77 is towards intersecting with axis 47, but this does not require especially.

Can recognize radially why cheap than tangential inlet inlet is.Especially, one radially enters the mouth is a hole that is arranged in the sidewall 71 usually, is fixed to the upper with a feed conduit or similar structure.

Still with reference to Fig. 1, assembly 1 comprises a preseparation arrangement 80.In general, by inlet port or enter the mouth and 12 enter after inner 18, preseparation arrangement 80 provides certain initially-separate of gas and liquid in gas/liquid flow.For shown in special construction, preseparation arrangement 80 comprise one the inlet baffle arrangement 82.

Put it briefly, the inlet baffle arrangement 82 of preseparation arrangement 80 is structure and location like this, when liquids and gases enter inlet 12 the time, they move by a curved path: this curved path is tending towards driving a part of liquid and enters deflection plate or wall construction, so that collect and discharge gas stream; And its guiding gas (gas/liquid mixture) enters a preferred flow path so that separate.In general, purpose is to obtain significant gas/liquid separation, and gas does not have unfavorable limited degree by maintainable separator unit 9 then.

Many air/oil separators that are used for compressor are used for such environment, and wherein, inlet stream not only comprises the oil particles that is entrained in the gas, and comprise the liquid oils stream of a large amount of reunions.The such one oil stream that enters separator assembly 1 can be on the magnitude of per minute 8 to 100 Jie's logical sequences (be about 30-380 liter/minute).Therefore, assembly 1 must be configured to control the oil stream of a large amount of reunions, together with separating of gas stream and gas/liquid.

Shown in special inlet baffle arrangement 82 comprise: axial shroud 85 and inlet radial skirt 86.Axial shroud 85 preferably comprises an outer surface 36a facing to wall 71.Therefore, axial shroud 85 is preferably cylindrical, and is radially continuous best.

Inlet radial skirt 86 roughly ringwise and radially outwards (with respect to axis 47) extend to extension between the inner surface 87 of axial shroud 85 and shell wall 71.Will become apparent that from following the particularly preferred inlet radial skirt 86 that is shown among Fig. 3 radially is not continuous.Inlet radial skirt 86 forms pathway 92 (not as seen, seeing Fig. 2 among Fig. 1).In this example, following pathway 92 includes the part of bore in apron 86, and it opens wide the space between axial shroud 85 and sidewall 71.Can use the downcomer of various variations, comprise a single space 93 shown in downcomer be a traditional example.

In general, in Fig. 2, the preseparation arrangement of a part is shown, it usually comprises the part that is attached to sidewall 71 and suspends from sidewall 71.In Fig. 3, inlet radial skirt 86 is shown.

With reference to Fig. 2, inlet radial skirt 86 preferably comprises a upper surface 86a, and the surface that it is configured to the inclination of a radial discharge causes collection liquid thereby thereon to help gravity towards the radially outward edge 86b of apron 86 discharging.Like this, be collected in liquid on the surperficial 86a and will be tending towards inner surface 87 dischargings towards the sidewall 71 of Fig. 1.This will comprise the oil stream of reunion.

Referring again to Fig. 1, when gas/liquid combination by entering the mouth 12 when entering pressure vessel 5, initial inlet stream is inducted into inlet baffle arrangement 82.In inlet baffle arrangement 82, gas stream is initially directed toward axial shroud 85 and inlet radial skirt 86.The a part of liquid that is included in the gas stream will be tending towards being collected on coaming plate 85 and the radial skirt upper surface 86a.Because the gradient or the inclination (having a down dip) of downcomer and apron 86,87 the extension from coaming plate 85 to wall, the liquid of collection will be tending towards flowing towards outer wall 87 under gravity.Finally, liquid will be discharged into downwards in the lower sump 40 from regional 98 (be formed on skirt upper surface 86a top) by following pathway 92.In general, pathway 92 under the gas stream flow direction that will be convenient to reunite.

With reference to Fig. 2, the edge 86c of radial skirt 86 generally is positioned on the axial height identical with edge 86d.This will be one to be convenient to the structure made especially, its technology such as hereinafter summary.If necessary, edge 86c can be positioned at slightly low than edge 86d so that liquid surfacewise 86a towards pathway 92 dischargings down; And under passing through, after the pathway 92, be convenient to gas stream and in zone 26, keep the mobile of a spiral.

12 is the 12a that radially enter the mouth because enter the mouth, so, be not automatically directed into the form of a helical flow towards central shaft to 47 the initial flow that enters the gas/liquid combination in the pressure vessel 5.Be incorporated into a spiral form in order to impel to flow, inlet baffle arrangement 82 comprises a radial flange or blade 100 (Fig. 2).Bead or blade 100 extend upward along the direction relative with the incline direction of radial skirt 86 from surperficial 86a, and operate in operating process and close the direction that may flow of inlet gas.For ad hoc structure shown in Figure 2, bead 100 be positioned to prevent anticlockwise flow (that is, and when the lid 7 of the assembly in Fig. 1 and 21 downwards, when the direction of arrow 105 is watched, be counterclockwise).(certainly, equipment can be configured to flowing of relative direction).Be expected bead 100 and be positioned to usually be not more than 45 °, generally be not more than 30 ° from the spaced radial or the distance at inlet 12 nearest edge.Really, the preferably as close as possible inlet 12 of blade 100 positions.In Fig. 2, the apparent position of inlet 12 is shown as 126, for the preferred embodiment shown in Fig. 1-3, preferably, blade 100 is positioned to spaced radial along gas flow direction, sows discord 93 at least 200 ° in crack, be generally at least 230 °, more preferably be at least 250 °.

Still with reference to Fig. 2, for shown in ad hoc structure, axial shroud 85 comprises the part 110 of the outer surface 36a of wall 36.In addition, axial shroud 85 has a continuous exterior surface 85a radially, is cylindrical in this example, therefore forms an annularly flow zone 111 (Fig. 1) between coaming plate 85 and wall inner surface 87.It is cylindrical not requiring axial shroud 85 especially.Yet, when relating to a single cylindrical separator 10 and using a cylindrical outer wall 71, normally and preferably will use a columniform coaming plate 85.

With reference to Fig. 1, preferably relief valve tap 45 extends through wall 71 and is communicated with flow region 111.Normally and preferably relief valve tap 45 is positioned near the blade 100 of Fig. 2, (replaces being positioned at as illustrated in fig. 1 from inlet 12 surrounding walls 71 about 180 °) on the opposite side of inlet 12.In Fig. 2, relief valve tap 45 is positioned at adjacent domain 112 or overlapping region 112.

Can predict the zone that a total cross-section can preferably be provided zone 111 in some instances, promptly, provide cross section to the space that is formed by outer wall 71, installing ring 35, coaming plate 85 and inlet radial skirt 86, its area that has roughly area of section or the inlet area with inlet 12 is identical.Like this, around the flowing velocity of ring cavity 111 with respect to will not increasing significantly by 12 the flowing velocity of entering the mouth.In this zone, avoid the big increase of flow velocity normally preferred, because it helps avoid the liquid (entering in the gas stream) of carrying separation secretly.

In addition, preferably avoid the big reduction of flow velocity in zone 111, to avoid the loss of centrifugal force, by driving fluid drips facing to wall 71, centrifugal force is used for separating some drop, and gas flows around coaming plate 85.

For typical preferred structure, the upper surface 86a of radial skirt 86 will be with inclination angle A from waist or inward flange or zone 113 to outward flange or perimeter 114 radially extension extend (Fig. 2), it is at least about 20 ° magnitude, common angle (comprising 20 ° and 80 °) in 20 ° to 80 ° scopes, (for example, be generally 30 °-60 °, for shown in particular instance be 40 °-50 °).Term in this example " inclination " and its variation mean, when structure makes floss hole 16 towards one of following time downward angle for normal use orientation.In general, select the effect of an inclination angle A part to be, guaranteeing provides suitable cross-sectional area in zone 111.In addition, it is selected with the flow velocity of promotion bulk liquid or towards wall 71.

In general, preferably in shell 1, as far as possible reasonably locate the height of radial skirt 86, the size of ring cavity 111 be should be taken into account above-mentioned preferred property.The reason of first-selected high as far as possible installation is, the surface area that preferably makes the wall 71 in the zone between the lower limb 36b of the bottom side 86e of the radial skirt 86 among Fig. 1 and coaming plate 36 is for maximum.The maximization of the surface area of this position wall 71 will be convenient to air with the form of rotation during by pathway 92 down liquid carry out centrifugation, and below the lower limb 36b of coaming plate 36 by beginning to enter hole 33.

Preferably, the edge 86b of radial skirt 86 be positioned at from the lower limb 36b of coaming plate 36 towards the distance of installing ring 35 at least 35% (promptly, the axial length of coaming plate 36 or coaming plate 85 35%), be at least 40% of this distance more preferably, be generally at least 50% of this distance.

Shown in preferred embodiment in, the following pathway 92 of Fig. 2 is one to be arranged on the gap in the radial skirt 86, it fully extends (Fig. 1) between coaming plate 85 and wall 71.The advantage of this structure is that when liquids and gases flowed downward by following pathway 92, gas did not expand towards coaming plate 85 or wall 71, and the risk of entrained liquids is arranged once more below radial skirt 86.Normally and preferably, the radial width X of following pathway 92 will be the radial skirt 86 between interior waist or edge 113 and the outward flange 114 (or 86b) extension distance at least 90%.Preferably being at least 95% of this distance, is 100% (as shown in the figure) of this distance best.

Following pathway 92 approximate location of Fig. 2 start from 93a place, edge, its with respect to inlet 12 center line 47 (Fig. 1) at interval in radial position place (along the direction of gas stream), intersect at least 70 ° angle, typically be at least 180 °, be generally at least 230 °, for example, be shown as about 250 ° to 340 ° around coaming plate 85.Moreover, the gap or down pathway 92 from blade 100 at least 200 ° of spaced radials preferably, particularly preferably at least 230 °, typically at least 250 ° (along the gas flow path direction).This will help gas stream to leave the fluid separation applications amount that cyclone separator arrangement 80 provides increase before.The radical length Y of radial skirt 86 and following pathway 92 usually as requested flow velocity and the restriction of descending pathway selected, be generally and be not more than 130 ° radially extension at least about 30 °, typically be 30 ° to 80 ° (comprising 30 ° and 80 °), for example, will adopt about 40 ° to 60 °.Here the employed term of coverage " comprises " and is meant that endpoint value is also included within the described scope.Even this term does not use particularly, the scope of all descriptions all is intended that the implication of " comprising ".

As mentioned above, described principle can be applicable in the various unit of various sizes and application.Show following size is how to use present principles for the ease of understanding.For example, if assembly 1 is used for a compressor, this compressor has engine power rating and the about 500cfm (about 236 of about 125hp (about 93Kw), 000cu.cm/sec) expection output, then this unit can constitute like this: shell has overall diameter and (for example is about 9-11 inch (22.8-28cm), 10 inches or 2.5cm) and total height be about 40-45 inch (being about 101cm-115cm), (for example, 42 inches or 107cm); One separator 10 has length and (for example is about 20-25 inch (being about 50-64cm), 22 inches or 56cm), one overall diameter (for example is about 5-6 inch (being about 12-15.3cm), 5.5 inch or 14cm), and one interior diameter be about 3-4 inch (being about 7.6-10.2cm) (for example, 3.5 inches or 8.9cm).Bottom 37 and the distance of cheating between the liquid level 41a in 40 are roughly selected like this: make this distance enough greatly, move prevention by gas towards hole 33 and carry the liquid that is collected in cheating again secretly; And distance is enough short so that the total height minimum of assembly 1, convenience easy to use and saving cost.Typical distance is the magnitude of the 30%-60% of liquid depth.

With reference to Fig. 1, should be noted that, following way can provide a significant advantage, at least 20% the distance that makes wall 36 longitudinally extend the axial length of separator 10 along separator 10, or the installing space that separator 10 is located is preferably at least 35% of this distance.The reason of doing like this is, this for inlet 12 and ring cavity 111 form one effectively with preferred positions so that separates, simultaneously minimum is reduced in the bottom 37 and the distance of cheating between the 40 interior liquid level 41a.

Preferably, wall 36 is longitudinal extension separator 10 about 60% greater than separator 10 length not, or the installing space of separator 10 location preferably is not more than 50% of this length.Its reason is, wishes the flow velocity in the retaining zone 25, makes it not be tending towards carrying secretly again the liquid that is discharged in the hole 39.(the per minute actual cubic feet promptly, is not free air tolerance with compressed air, or is about 18 that 900cu.cm/sec) total flow on the magnitude realizes significant gas stream usually, does not have unfavorable degree of carrying secretly again to about 400ACFM.

With reference to Fig. 3, one as radial skirt 86 effective preferred inlet radial skirt 115 shown in the figure.Apron 115 is preferably single, one, a radially discontinuous ring structure that has a blade 100.It is formed by single metal sheet usually, for example, forms with pressure processing.For example, can use No. 18 steel (0.05 inch thick or 0.13cm is thick).For example, be fixed by arc welding in place.
